I'm not sure the term insufferable boor is quite adequate here, I'm not saying that he's entirely without humor, but it's the sort of humor that is always tempered by a reminder of how much money he has and how he is holding it over his adult children.

In his 840-page memoir, "The Missing Peace: The Inside Story of the Fight for Middle East Peace," published in 2004, he harshly criticized both former Israeli prime minister Benjamin Netanyahu (who was "insufferable" because of his uncompromising views, Ross said) and then-Palestinian leader Yasir Arafat for failing to relinquish their mutual "myths."

THERE’S nothing wrong with self-pity. As a spur to songwriting, it’s right up there with lust, anger and greed, and probably better than the remaining deadly sins.
